got rid source files that were not being used.
Separated the enrichment results parsers into separate parsers.  Added a class to determine the parser.  If the parser is GREAT then observer will ask user how they want to filter the results (binomial, hypergeometric,both or either).
Added scientific notation option to the input interface
Enabled sliders to work with cutoffs that had precision better than 10-3. Tried to get the lower limit closer to the actual minimum but the range can be huge making this difficult.  In the mean time it works with lower numbers and will filter from the cut-off to a precision less than 10-3.
